Description
Technical field
The present invention relates to the catalyst that a kind of hydrogenolysis of glycerin prepares 1,3-PD, specially WOx
Carrier loaded active component molybdenum oxide and platinum.
The invention is related to the preparation method and applications of above-mentioned catalyst, specially using solvent heat
Method prepares WOx, active component platinum and molybdenum are supported using two step infusion processes, and investigate not
The activity in hydrogenolysis of glycerin prepares 1,3- propane diols and selection with the catalyst under preparation condition
Property.
Technical background
With developing rapidly for biodiesel, the by-product glycerin in production biodiesel process is big
Amount is superfluous, and glycerine converting prepares high value chemicals turns into lifting Biodiesel economy
Effective means.Glycerine can generate 1,3-PD, 1,2-PD etc. by hydrogenolysis,
Wherein 1,3- propane diols is the important monomer for producing PTT (PTT).
PTT is a kind of new type polyester fiber with biodegradability, and it overcomes poly- terephthaldehyde
Sour glycol ester (PET) too hard and polybutylene terephthalate (PBT) (PBT) is too soft to be lacked
Point, while have excellent resilience, chromatophilia, biological degradability etc., thus carpet,
The industries such as Textile Engineering plastics have huge development potentiality.The industry of current 1,3- propane diols is raw
Product method has the oxirane carbonyl hydrogenation method and Degussa and Dupont of Shell companies
The acrolein hydration hydrogenation method of company.
Oxirane carbonyl hydrogenation method (Chinese patent CN1201407A) uses oxirane
3-HPA is generated with synthesis gas under cobalt-base catalyst, then by 3-HPA and hydrogen
The method of 1,3- propane diols is hydrogenated under hydrogenation catalyst effect.Acrolein hydration method (in
State patent CN93114516.3) it is dehydrated under solid acid catalyst using gaseous state glycerine hydrate
Generation methacrylaldehyde, the methacrylaldehyde of generation is hydrated generation 3- hydroxyls third under acidic catalyst effect
Aldehyde, the 3-HPA of generation under conventional hydrogenation catalyst Hydrogenation for 1,3-PD, together
When by-product 1,2- propane diols.
Above-mentioned industrial manufacture process is complicated, and environmental pollution is serious, and gained 1,3-PD contains
Impurity, needs further purified treatment.
Document (Appl.Microbiol.Biotechnol.1992,36,592-597) reports one
The method that 1,3-PD is prepared using Clostridiurn strain bio conversions is planted, can be in 29h
The glycerite conversion of 110g/l is obtained into the 1,3- propane diols of 56g/l afterwards, the method is subject to biology
The influence of metabolic activities, low production efficiency, and because production concentration is low, purifies and separates
Energy consumption needed for 1,3- propane diols is also very high.
Document (Catal.Commun.2008,9,1360-1363) reports one kind in 1,3- bis-
Methyl -2- imidazolones are under solvent, hydrogenolysis of glycerin prepares the method for 1,3-PD, the method
The yield of 1,3- propane diols is 24%.
The Tomishige seminars of Japan report the Rh/SiO of Re modifications2And Ir/SiO2Urge
Agent, author is in Ir-Re/SiO2Fluid sulphuric acid (H is added under catalyst action+/ Re=1), hydrogen
Gas initial pressure 8MPa, at 120 DEG C of reaction temperature, 36 is reacted in 20% glycerine water solution
After h, the high income of 1,3-PD up to 38.0% has been obtained.Subsequent literature (Journal of
Molecular Catalysis A:Chemical.2014,388,177-187) the 3rd is also reported to help
Agent especially Ru it is prepared by hydrogenolysis of glycerin 1,3- propane diols facilitation it is most obvious.
The Jinho Oh of South Korea report the ZrO that Pt is supported on sulfuric acid acidifying2On, with DMI
It is reaction medium, is 7.3MPa in initial hydrogen pressure, 24h is reacted at 170 DEG C of reaction temperature
The high income of 1,3- propane diols up to 55.6% is obtained.
Organic solvent is employed in above-mentioned reaction as reaction medium, and the annex solution for being used
The method of body acid, does not meet the requirement of Green Chemistry.
The direct hydrogenolysis of glycerine prepares 1,3-PD and has obtained very big concern in recent years, because its work
Skill is simple, and raw material is cheap.Document (Chin.J.Catal.2012,33:Although 1257-1261) reporting
A kind of simple mesoporous WO of Pt/3The catalyst of hydrogenolysis of glycerin 1,3-PD is directly used in,
But the overall yield of 1,3- propane diols is still relatively low.So far, document (ChemSusChem
2013,6,1345-1347) it is 100% and the performance of selectivity up to 66% to report conversion ratio
Optimal Pt/WOx/ AlOOH catalyst systems.But it is converted into unit noble metal catalyst unit
For the 1,3-PD yield that time obtains, reduced levels are still in.Also there is text simultaneously
Offer (Journal of Molecular Catalysis A:Chemical.2015,398,391-398) report
Road WOxTo Pt/Al2O3Facilitation.Document (Chem.Lett.2012,41,1720-
- 1722) AlO is reportedxTo Pt Nanoparticles/WO3In hydrogenolysis of glycerin 1,3- propane diols
Facilitation.Even author has also investigated MoOxTo Pt Nanoparticles/WO3Promotion
Effect, unfortunately, in this document, MoOxAddition on the contrary show whole catalyst
Any activity is not gone out.The facilitation and WO of possible auxiliary agentxStructure and the dispersiveness of Pt have
Substantial connection.Whole catalyst system and catalyzing is made a general survey of, current study hotspot is concentrated mainly on Pt/W/Al2O3
System simultaneously develops towards auxiliary agent addition direction.Either improve the pattern of each species, content is still
Crystalline structure sets auxiliary agent species, there is the raising of different degrees of 1,3-PD yield, reacts
Solvent is also generally fixed to the water phase condition of environmental protection, but is all also maintained at pressure higher substantially
(5MPa is in the majority, highest 8MPa) and temperature (180-200 DEG C) higher.In order that glycerine
Direct hydrogenolysis prepares that 1,3-PD reaction condition is gentleer, and yield is further improved, it is necessary to
New catalyst system and catalyzing is further developed on the basis of existing.
